Questions & Answers

As answered by people managing Snapvi and ImageOptim.

What makes your product unique?

Snapvi's answer

Snapvi runs 100% in your browser — every image, PDF, video and audio task is processed on your own device, so your files are never uploaded to a server. That means real privacy, no sign-up, no watermark and no file-size limits, while still offering AI tools like background removal, 2×/4× upscaling and photo sharpening. It's also an installable PWA that works offline, in English and Vietnamese.

Why should a person choose your product over its competitors?

Snapvi's answer

Most online tools upload your files to their servers; Snapvi doesn't — everything happens locally in your browser, so it's genuinely private and instant. It's completely free with no account, no watermark and no size limits, bundles 40+ image, PDF and video tools in one place (including an AI background remover, upscaler and sharpener), and works offline once installed.

How would you describe the primary audience of your product?

Snapvi's answer

Anyone who needs quick image or PDF edits without installing software or uploading private files: students and office workers preparing documents and ID/application photos, content creators and social-media users, small businesses, and privacy-conscious people. The site is bilingual (English + Vietnamese) and popular in Vietnam and worldwide.

What's the story behind your product?

Snapvi's answer

Snapvi started from a simple frustration: most free online tools make you upload private files — IDs, documents, personal photos — to a server just to compress or convert them. We wanted a toolbox that does everything on the user's own device instead. Using modern browser technology, Snapvi runs 40+ tools fully client-side: fast, free and private by design.

Which are the primary technologies used for building your product?

Snapvi's answer

A 100% client-side web app with no backend for file processing. Built with vanilla JavaScript and the HTML5 Canvas API; pdf-lib and pdf.js for PDF tasks; TensorFlow.js / WebGL for AI (background removal, upscaling); the Web Audio API for audio. It's a PWA (service worker for offline use), hosted as a static site on Cloudflare Pages.
